[AccessD] Double Data Entry Requirement

Double Data entry used to be done by two separate operators even going 
back to the old IBM 029 card key punch verifiers (which didn't punch 
only read)
and the later key to disk systems. As the same operator may read a 9 as 
an 8 both times. Not to mention there were batch totals kept  i.e. 
number of sheets punched to ensure an operator didn't skip a sheet in a 
batch. Most data entry errors are caused by transposition of digits. 
Hence the use of checkdigits
for things like ISBN,VIN, credit cards and social security number (but 
not in US)
You might want to consider optical scanning unless the data is coming 
from handwriting.
